with that sort of power, i am assuming that it is probably a drag car. if not, i would personally buy and xr6T or xr8. you need to remember one thing about projects...they cost big bucks. it is cheaper to buy a car that someone else has built and sunk the money into.
my project car, the RS2000, was purchased as a shell, and i have bought all of my parts second hand, except front indicator lenses which were new from the UK, and it has cost me about $6000. and it isnt on the road yet! there is more to come. the car came with no mechanicals, so i purchased a van as a donor vehicle.
unless you really have to build this car, look at the alternatives first.
You wash your car like it was your firstborn child, you tend to its needs like it was your own body, you protect it like it's your family, then you drive it like you stole it.
